If you have the program fully updated, with all the data files, you should have a variant data file called "Variant Basic Set 4e - Metric Equipment". To load it, go to Tools - Options - Data Sets, and click Change. You'll be given a list of data sets to add to the list, which should include the file I mentioned. Once you add it, click "Load Now". Your character details should now appear in metric.

Thanks, but since I've told, I'm using GCB(I just didn't find a board for it), and using 3e still, since they have not yet translated the basic set to my own language(but they will...I know they will..hehe)

I don't know whether the answer is there or not, but you could try going to the Meacreator Website (GCB is a specialized build of Metacreator that was licensed by SJ Games for 3rd edition), and looking on their Discussion Board, or possibly the FAQ. Failing both of those, I believe there is a Support contact thingy at the bottom, and someone with Alterego Software may be able to help you out.

in GCA is there any character sheet that will print just like the 3d edition sheets?

Well, GCA4 supports custom character sheets, so making a sheet like that is possible. However, I don't think that anyone has created a sheet like that yet (assuming that you mean the basic 3e sheet: front & back).
